Okay, so Defend The Sewers is one of those weirdly addictive little HTML5 games where you play as Craig and his friends from Craig of the Creek, holding off waves of sewer creatures. It's simple—pick a character, set up defenses, and try not to get overrun by mutant rats and whatever else crawls out of the pipes.

At first, I thought it was just another basic tower defense thing, but the upgrades and different character abilities actually make it pretty strategic. Like, Kelsey’s arrows are great for picking off stragglers, but JP’s bombs? Absolute chaos (in the best way). The pixel art’s charming, too—feels like something the kids would actually build in the show.

Fair warning: the later levels get brutal if you don’t plan ahead. I learned that the hard way.
